CHARLES Ii. HUNT AND NE'ITER J. HILL, OF ST. LOUIS, MISSOURI, ASSIGNORST0 NON- REFILLABLE CONTAINER, INC., OF ST. LOUIS, MISSOURI, ACORPORATION 0F MIS- SOURI VALVE ron LIQUID CONTAINERS Application ledNovember 25, 1929, Serial No. 409,474. Renewed December 27, 1932.

VThis invention relates to valves for liquid containers and has specialreference to containers tor confining liquid to be shipped ortransported while in the containers, and for confining liquid to bewithdrawn from the containers tor use or sale.

An object of the invention is to provide a container with an improveddevice controlling withdrawal of the liquid from the container andmaking it impossible or highly ditcult to reiill the container,comprising a pipe extending through one end of the container toward theopposite wall and having its inner end open, so that the contents of thecontainer may pass into the pipe for withdrawal, in combination with anovel valve device mounted in and supported by the inner end of thepipe, permitting withdrawal ot the contents of the container and makingit impossible and highly difficult to reill the container.

Another object of the invention is to v.provide means of the type andcharacter mentioned in various specific forms, so as to obtain thedesired results in the most efficient manner.

Other objects will appear from the following description, referencebeing made to the accompanying drawings in which- Fig. l is a viewshowing a container equipped with the present invention.

Fig. 8 is a vertical sectional view showing the valve controlled pipeand a novel form oi detachable connection and seal for holding said pipein proper relationship with the container.

Fig. 9 is a cross sectional view approximately on the line 9-9 of Fig.7.

Y Fig. l0 is an outer end elevation of the construction shown in Fig. 8.

The container, as shown in Figs. l to 8, inclusive, is a barrel offamiliar construction including a shell 1, a top wall 2 and a bottomwall 3. The top and bottom walls are shown outwardly convexed and thewithdrawal pipe is shown mounted axially in the barrel, whichrelationship may be changed and varied, as desired, without departurefrom the invention.

A withdrawal pipe 4 extends through a hole in the top wall 2 andterminates adjacent to the bottom wall 3. This pipe may be permanentlysecured to one or to both wallsy of the container and, as shown, is:permanently secured to the top wall 2, an impervious joint between saidpipe 4 and said top wall 2 being obtained by a ring of solder 5A appliedto the joint.

The lower end of the pipe 4 is shown spaced slightly from the bottomwall 3 of the container and also provided with notches or openings 6,said space and said notches or openings forming a passage so as topermit the liquid contents of the container to enter the lower end ofthe pipe 4 to be withdrawn, or to permit the liquid to pass through thepipe 4 and through said passage to ll the Container initially. Theinside of the pipe 4, at its upper end, is threaded and is closed by aremovable pl-ug 7 during shipment or when the container is in storage.This plug may be removed and the usual threaded attachment ot a pump(not shown) may be screwed into the end of the pipe 4 to with-v draw theliquid contents from the container.

A support for a valve seat is attached to the inner end of the pipe 4.This support may be made of various forms. The support, shown in Fig. 2,comprises a ring 8 mounted on the inside of the pipe 4 at the inner endoi said pipe and having extensions 9 bent across and embracing spacedportions of the inner end of the pipe 4. These bent extensions 9 areclamped upon the end of the pipe 4 and exemplify means for rigidlyhold-` ing the ring 8 in connection with said pipe 4.

The ring 8 is formed with an internal shoulder 10 and this shoulder 10forms a seat for a valve support. In the embodiment shown in Fig. 2, thevalve support is a cage comprising an inner Wall 11 provided with acentral hole 12. and with a circumferential fiange 13; an outer Wall 14having a cent-ral hole 15 and a circumferential flange 16; and a ring orcylindrical portion 17 onto which the flanges 13 and 16 are telescopedand secured, so as to provide a unitary structure for supporting andconfining a spherical valve body 18. The valve 1S is prevented fromclosing the hole 15 b v abutments 15a. The ring 8, at its outer end, hasextensions 19 that are bent inwardly to form abutment-s Jfor the Wall14, so as to prevent outward movement or displacement of the valvesupport from its seat on the shoulder 10.

The valve 18 is confined Within this valve support and when thecontainer is in upright position, said valve seats upon the marginaledge of the plate 11 around the hole 12, so as to close said hole andthus effectively prevent liquid from being poured into the container.The valve is too large to pass through either of the holes 12 or 15, sothat it is impossible for the valve to Work out of the support.Operation of a suction pump Will, as is clear, Withdraw all liquid fromthe container smproximatelyT to the lower side of the valve device. For,when the pump operates, the valve 18 is opened and the liquid contentspass, or are drawn, into the pipe 4 above the valve and thence outwardlythrough the pipe 4. u

In Figs. 5 and 6, a hinged or pivoted type of valve is shown inconnection with the valve support for permitting Withdrawal of theliquid contents of the container and preventing refilling of thecontainer. As shown in Fig. 5, a pipe 2O extends through a hole in thetop Wall 2 toward the bottom ivall 3, an impervious joint .vith the topWall being obtained by a ring of solder 21. The valve support comprisesa ring 22 mounted Within the inner end of the pipe 20 and havingextensions 23 bent across and embracing spaced portions of the inner endof the pipe 20. These bent extensions 23 are clamped upon the end of thepipe 20 and exemplify means for rigidly holding the ring 22 inconnection with said pipe 20.

The ring 22 is formed With an internal shoulder 24 and this shoulder 24forms a seat for a valve support. In the embodiment shown in Fig. 5, thevalve support is cage comprising an inner Wall 25 provided With acentral hole 26 and with a circumferential flange 27; an outer Wall 28having a central hole 29 and a circumferential flange 30; and a ring orcylindrical portion 31 onto which the flanges 27 and 30 are telescopedand secured, so as to provide av unitary structure for supporting andconfining a. disc valve 32.

rFhe disc valve 32 is connected with the plate 25 by a hinge device 33,which permits the disc 32 to move from and to closed and open positions.ln closed position, the valve plate 32 is sea-ted upon the plate 25 andcompletely closes the hole 26. ln open position, the valve plate 32 isinclined, extent of movement of said valve plate 32 toward open positionbeing limited by an abutment 34 attached to the ring 31. The ring 22, atits outer end, has extensions 35 that arc bent inwardly to formabutments for the Wall 23, so as to prevent outward movement ordisplacement of the valve support from its seat on the shoulder 24.

In F igs. 7 and 9, a still dierent type of valve support and valve areshown. In this construction, a pipe 36 extends through a hole in the topWall 2 toward the bottom Wall 3, an impervious joint with the top Wallbeing obtained by a ring of solder 37. The valve support comprises aring 38 mounted Within the inner end of the pipe 36 and havingextensions 39 bent across and embracing spaced portions of the inner endof the pipe 36. rlhese bent extensions 39 are clamped upon the end ofthe pipe 36 and exemplify means for rigidly holding the ring 33 inconnection With said pipe 36.

rlhe ring 33 is formed with an internal shoulder 40 and this shoulder 40forms a seat for a. valve support. In the embodiment shown in Figs. 7and 8, the valve support comprises a body 41 confined within the outerportion of the ring 38 and seated upon the shoulder 40 and havingtherethrough a port 42. rlhe port 42 is crossed by a web 43 formed witha central guide 44 through which a valve stem 45 extends forlongitudinal sliding and for turning movements. The outer end of thevalve stem 45 has attached thereto a disc valve 46 having a beveledseating surface 47 arranged to seat upon the valve seat 43 formed aroundthe outer portion of the port 42. The valve stem 45 projects through theguide 44 and its inner portion is encircled by a spring 49. One end ofthe spring 49 abuts against the guide 44 and the opposite end of saidspring 49 bears against an abutment 50, which may be a pin extendingdiametrically through the stem 45, as shown. The power and resiliency ofthe spring- 49 is suilicient to hold the valve 46 seated upon the valveseat 48, but will yield to the pressure of the liquid Within thecontainer When a pump is operated to Withdraw the liquid from thecontainer. For, in this embodiment of the invention, a plug 51 isscrewed into the outer end of the pipe 36 and is removable to permit theattachment of a pump member, as the plug 7 is removable from theconstruction shown in Fig. 2 and as the plug 20"L is removable from theconstruction shown in Fig. 5.

The valve device, shown in connection llf) said valve support iformedintegrally gral with said supporting element eXtendin with the pipe 52(Fig. 8), is like the valve device shown in Fig. 2 and has the' samereference numerals applied thereto. The outer end of the pipe 52 isattached to a fitting 53. In the specific embodiment shown, the iitting53 has a portion 54C telescoping within the outer end of the pipe 52,and provided with a hermetic joint by means Vof a ring of solder 55located at the inner end'oif the part 5e. The end of the pipe 52 extendsinto an annular groove in the fitting 53, the portion 56 of said iittingthat encircles the outer end of the pipe 52 being provided with a ringoi' solder 57 to obtain an impervious joint.

A metallic ring 58 is rigidly attached to the top wall 59 of thecontainer 60 and is also rigid with an internally threaded ring 61. Thepart 56 oi the iitting 53 is externally threaded and screws into andthrough the rings 6l and 58, an impervious joint being obtained by agasketJ 62 clamped between the fitting 53 and the ring 6l. rlhe ring 58has a number of ears 63 having holes therethrough, and the fitting 53has a number of ears 6e having holes therethrough. A ifrangible sealbody 65 is formed about and to embed the ends of a strip 66 oi metal, orother appropriate material, which strip is passed through the holes inthe ears 63 and 64. Thus, a destructible seal is provided which may beattached to the device, so as to prevent removal of the pipe 52 from thecontainer without leaving evidence indicating that fact. A plug 67 isscrewed into the fitting 53 and may be removed to permit insertion ofthe usual threaded attachment of a pump.

It is now clear that our invention may be embodied in various forms inwhich the valve is supported in and forms a part of the pipe device andwhich may be attached to the container as unit. rlhat is to say, thepipe device and the valve supported therein constitute a self-containedunit removable from and attachable to the container, so that no care isrequired to obtain proper location oic the pipe with respect to thevalve after the pipe and valve are assembled together before attachmentto the container. rlhe construction may be varied in other respects asspecifically shown and described.
